efi live help
im a new user to efi live and have had no sucsess tuning i have a 1998 to 2002 conversion with the van map programed in. the car seems to run fine but i can tell that its running a little rough.
i tryed advncing timing by 3 i upped the fuel by 3 in the high rpm and droped it by 2 in the lower. i also added a little dwell by 1 milli and upped the maf tables by 1 it still seems to run the same but a little more responsive with low end when i do the same tune as above with out maf and adding fuel to the table at low and high smothining the peeks as much as i can i get a car with less tourqe and more spin in the mid end.
if you have any tuning tips for me let me know

I did the same swap. How did the car run before you swapped? Was it tuned for your mods? Which tune did you use as a base tune? I initially used a tune off of holdencrazy which migrated a 99 tune to a 2002 Operating system. My car actually ran better with that tune than it did with a professional tune. I just needed to tweek the idle, and lower the timing a little cause of my turbo. If your car was tuned before you can migrate the old settings to the new tune, mostly VE, spark, and MAF.
